SPlNDLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 508,742, dated November 14, 1893.

Application filed June 1'7, 1893. Serial No. 477,910. (No model.)

pintles are put into bolsters held in support-" ing cases shaped to receive oil and supply it as needed to the bolster and spindle, and so also the spindle has to be restrained so that it cannot be lifted from its bolster and the case accidentally in doffing and piecing.

I have provided the sleeve whirl with an extension in which is made an annular groove adapted to be entered by, an eccentric key or locking device, and I prefer to make the key or locking device of such form that a projection carried byit will close the oil chamber leading to the supporting case.

Figure l,- in elevation shows a spindle and supporting case embodying my invention,

the curb being broken out in about the line" :0, Fig. 2. Fig. 2, is a detail of the upper end of the supporting case, partially broken out; and Fig. 3, is a section in the line 00, Fig. 2.

The sleeve whirl spindle A has at the bot-.

tom of the sleeve A an extension A provided with an annular groove, as best shown in Fig. 1, said extension entering the curb B at the upper end of the supporting case B having ashank B adapted to enter a rail, not shown, of usual construction; At the junctionof the curb with the part of the-supporting case which sets on the rail I have provided the casting with an extension 0 in which I have bored a diagonal inlet 0' so that oil put in theiulet may run into the oil chamber d of the curb and stand at the same level in the inlet. The supporting case has a tubular upright central portion 13 which receives and supports the usual bolster, not shown.

By providing the extension 0 with a diagonal hole, as herein shown, it is necessary to bore but one hole, and that one does not need to be stopped permanently.

The curb is suitably bored to receive a locking device or pine, it being adapted to enter theannular groove of the whirl extension, and in such position affording an obdevice.

so that when said locking device is in the position shown in Figs. 1 and 2,aport-ion of the wire will stand in the groove of the extension, butwhen the locking device is turned over from its full line position, as represented by dotted lines Fig.2, then the cut away part 2 is so presented to the Whirl that the lower end or'the extension may pass above the locking I have provided the locking device at one end with a bent portion carrying a cap e, which, when the locking device is in Working position will cover the oil inlet, as shown in Figs. 2 and 3.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. A supporting case having a tubular central portion to act as a bearing for the spindle; a surrounding curb to constitute an oil chamber, said curb having a laterally extended arm provided with an open oil inlet,

said inlet leading into said chamber; and a sleeve whirl spindle having an annularly grooved extension below its wliirl, combined with a locking device made as an eccentric rocking pin provided with an attached cap, the said 'pin being mounted in a bearing formed in said curb and entering the said annular groove, the cap connected with the said pin covering the open oil inlet, substantially as described.

2. The sleeve whirl spindle having an extension provided With an annular groove,

and a supporting case having a curb outside "of the bolster-receiving tubular center of the in the whirl extension, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES HJNORTHROP.
